Yes, thats still all I have. I'm new to this so please pardon my ignorance. But I was under the understanding that barbs in general school well. So, as long as the overall school is 6+ you are good. So, 3 green, 3 tiger, 3 black ruby = 9fish school.

Please correct me if I'm wrong. Though, the 6 barbs I currently have all get a long great.

Barbs school with their own species. Greens and Tigers are the same species, just different color variants, so they will school together. Black ruby barbs are a totally different species so the same rules do not apply.

Very good to know. I guess a barb isn't always a barb.
Shocking, the bodies are very similarly shaped, so I figured they were the same species.
